lb all whom it y concern;

o it own that we, Pnncr R. Manonnr and War. R. Knunenn, citizens of the United States of America, residing at Portland in the county of Multnomah and State of @regon, have invented new and useful Improvements in Sandin Devices for Autovehicles, of which the ollowing is a specification.

llhe invention relates to sanding'devices for auto vehicles and seeks to rovade as its rincipal object, an improved evice wherey sand may be discharged at any time upon the tires of the traction wheels andupon the traction surface directly in front of the wheels, thereby preventing slipping and skidding.-

A further object of the invention is the provision of a sanding device for auto vehicles so arranged that the exhaust of the vehicle engine may be automatically dive from the mer into mechanism connected with a sand reservoirthereby causing the sand to he ejected onto the wheels and onto the traction surface directly in front of the V wheels.

A still further object of the invention is to provide means for attachment to the steering column at a point adjacent the steeg wheel, whereby the engineexhaust may be conveniently diverted from the mer into the sanding device and vice WE a it still further object is to provide a de-' vice of this character which is simple incon- 'struction, durable and efl'e'ctive in operation and which can be manufactured and applied to auto vehicles at small cost.

Other and further objects will appear'as the invention is set forth in detail in the in the accompanying drawings, the invention is illustrated in a speci c form to which it is not to be restricted. Actual practicalapplication may show certain desirable changes or alterations to he of advantage and the right is claimed to make any such changes or alterations that do not dieviate from the scope of the subjoined c a a W esame numerals of reference designate the same parts through the several figures of the drawings, wherein:

eferring to thedrawings, there is shown a conventional form of auto vehicle having a chassis l, the traction wheels 2, the steering column 3 and the steerin wheel 4 all of which are made and assemb ed in the usual way. I g a "0n the rear end of the chassis and positioned so that it will stand below the rear seat of the vehicle body when'the latter is secured to the chassis, there is a box or reservoir 5 which is designed to hold sand or some other gritt material which, when applied to the er into the sanding give to. both a high coeflicient of friction. The box or reservoir 5 is preferablyin the trea s of the wheels and to the-surface over which the wheels pass, will form of a rectangular parallelepiped having" an opening positioned centrally in its top 7!, this openmg being for the urpose'of supplying the box with sand. t the bottom of the forward endof the box and peel tioned adjacent each of its two sides, there are apertures or openings 8 through which the sand or frictional material is designed to pass when leaving the box. The bottom of thebox is arranged so as. to direct the sand or frictional material toward these openings, this arrangement comprising triangular bottom platesl) and 10. The box is provided with two of each of these plates and they are assembled in pairs consisting of one plate 9 and one plate 10. The two plates are in the shape of right angle tri angles and they are joined together on thestance which is placed into the box .finds its wa b avit to the o enings 8.

On zhe ur i dersu i'face of 51c box 5 elbows 11 are provided which connect with the openings 8 and these elbowstermmate in PS 12 to each of which a tube 13 is attached. Both the tubes-13 pass from the "PS '12 over in front of the treads of the wheels 2 where they terminatein nozzles 14 having outlets 15 through which sand or other itty material is ejected and blown onto t d treads of the wheels and onto the traction surface in front of the wheels. The two Ts 12 are interconnected by a pipe 16 which carries a T 17 at its center, the leg of this T 17 receiving a second pipe 18 which is connected with the exhaust pipe 19 leadin from the vehicle engine by means of the Y- tting 20. I

The exhaust pipe 19 carries the usual flap valve 21 between the Y-fitting 20 and the mufller 22. I

The Y-fitting 20 forms a housing for the flap valve 23 which is carried on a stem 24 that is pivotally mounted in the Y-fitting 20 at the junction of the leg with the body of the fitting. This flap valve 23 is designed to close communication between the exhaust pipe 19 and the ipe 18 or between the exhaust pipe 19 an the muffler 22, the fitting being provided with a projection 25 carried on its interior against which the valve 23 abuts when closing communication between the exhaust valve 19 and the mufiler.

- To keep the flap valve 23 normally in a position where it closes communication between the exhaust pi e 19 and the pipe 18, a lever 26 is attache to the valve stem 24 on the outside of the fitting 20 and this lever 26 has attached to its free end one end of the spring 27 the remaining end of which is suitably connected to the stra 28 attached on the pipe 18 near the point w ere it enters thefittmg 20.

The valve 23 is designed to be operated from the steering column and to that end 7 a tubular member 29 is provided which .lies

beside the steering column and passes down through the dash, curving back underneath the chassis of the machine where it ter minates in the vicinit of the fitting 20. This tubular member is designed to be attached and held in position in any suitable manner and it is made preferably of material which may be bent to the proper shape after having been inserted through the dash. This tubing 29 is designed as a shield and guide for a cable 30 one end of which is attached to the free end of the lever26, the

other end of the cable after the latter has been passed through the tube 29 being secured on the periphery of an eccentric member 31 adjacent the point where the operating handle 32 of the eccentric member connects with the latter. The eccentric member 31 is pivotally mounted on a stud 33 carried by a strap member 34 which is attached to the column 3 just below the steering wheel 4. The eccentric member 31 is grooved on its periphery, so that the cable 30 may lie therein when the eccentric member is moved b its handle 32. In this normal position 0 the eccentric member 31 and handle 32, the sprin 27 of the valve 23 holds the latter in t e position of closing the pipe 18. When the handle 32 is depressed, however, the cable 30 is drawn through the tube 29 and that portion of the cable which is drawn out of the upper end of the tube lies in the groove in the periphery of the eccentric member 31. Thus the lever 26 is moved and with it the valve 23 against the tension of the spring 27, the

valve 23 bein brought over against the projection 25, t ereby closing communication between the exhaust tube 19 and the mufiier 22 and opening communication between the former tube and the ipe 18.

It will be observe that the sanding device is held normally inoperative b the spring 27 which holds the valve 23 in the position of closin communication with the pipe 18 and whic also holds the handle 32 in its normal position. In this position of the valve 23, the exhaust from the engine passes into the tube 19 and thence into the muflier 22. In the event that it is desired to put the sanding device in operation to prevent skidding, it is only necessary to depress the handle 32, thus diverting the exhaust into the ipe 18 from which is passes through the pipe 16 and thence into the tubes 13, ejecting ahead of it the sand and grit which is forced by gravity into the Ts 12 through the openings 8 and elbows 11 the sand passing with the exhaust out through the openings 15 of the nozzles 14 by which it is distributed on the treads of the wheels and onto the traction surface just below the 116 wheels.
